title: N,N-Di-methyl-dehydro-abietyl-ammonium chloride ethanol monosolvate.
abstract: The title compound {systematic name: 1-[(1R,4aS,10aR)-7-isopropyl-1,4a-dimethyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenan-thren-1-yl]-N,N-di-methyl-methanaminium chloride ethanol monosolvate}, C22H36N(+)·Cl(-)·C2H6O, was synthesized from dehydroabietylamine by N-methyl-ation with formaldehyde/formic acid and transformation into the hydro-chloride. The de-hydro-abietyl moiety exhibits the usual conformation with the two cyclo-hexane rings in chair and half-chair conformations and a trans-ring junction. The crystal structure is built up from columns of the de-hydro-abietyl moieties stacked along the a axis. These columns are held together by the chloride ions via N-H⋯Cl and C-H⋯Cl inter-actions, which establish a two-dimensional network parallel to (010). The ethanol solvent mol-ecules are located between the columns and anchored via O-H⋯Cl hydrogen bonds.
